Anyone can provide a valid (and recent) stacktrace for this?

Install compiz-core-dbgsym compiz-plugins-default-dbgsym unity-dbgsym packages from ddebs repos¹.
When the hang happens, just do Ctrl+Alt+F1 and from tty1 one do something like:
  sudo gdb -p $(pidof compiz)

Once gdb is loaded, do a:
set logging file compiz-hang.txt
set logging on
bt full

Exit from gdb and attach the "compiz-hang.txt" file (or any other name
you chose) here.
